Abstract
In an adsorption operation in which the adsorption agent adsorbs water, air in a vehicle compartment flows into an adsorption agent module after being cooled by passing around a heat sink. On the other hand, in a desorption operation in which the water is desorbed from the adsorption agent, the air in the vehicle compartment flows into the adsorption agent module to be humidified without being heated or cooled, and humidified air is cooled by passing around the heat sink and blown into the vehicle compartment. Accordingly, a temperature of the humidified air can be prevented from increasing unnecessarily by a simple configuration with which the air in the vehicle compartment is cooled in the heat sink.
Claims7
A humidification device for humidifying a humidification-subject space, the humidification device comprising:
- a polymeric adsorption agent that adsorbs water in an adsorption operation and desorbs the water in a desorption operation;
- a cooler cooling an adsorption air that includes the water to be adsorbed on the polymeric adsorption agent;
- and
- a blower blowing the air in the humidification-subject space, wherein
- in the adsorption operation, the cooler decreases a temperature of the adsorption air to be lower than an air temperature in the humidification-subject space, and
- in the desorption operation, the water adsorbed on the polymeric adsorption agent is desorbed to the air, the air flowing from the humidification-subject space without being heated or cooled,
- the adsorption operation and the desorption operation are switched by switching between (i) a ventilation passage through which the air blown by the blower flows to the polymeric adsorption agent after being cooled by the cooler and (ii) the ventilation passage through which the air blown by the blower flows to the polymeric adsorption agent without being cooled by the cooler.
